Changed contour labels by removing the black bounding box and changin…

…g the font color to black. This avoids proliferating labels from obfuscating other data. The number of contours for MSLP on large domains was reduced for the same reason. Also, the new temperature color table developed by Craig is included to make this consistent between models. These changes were in response to an email from Tanya concerning these issues.
